The radius of the disk is R, and the mass of the disk is M. Using the parallel axis theorem and theequation for the moment of inertia of a disk about its central axis developed in the previous example, Eq. (8), the moment of inertia of the disk about the specified axis is Fig.
Short Circuits. Short circuits are the second most common reason for breaker tripping and are a more serious concern. Short circuits occur when the black hot wires inside your electrical service panel come in contact with either other hot wires or neutral wires.
Voltmeter immediately reads 18v or higher when powered on. The most common cause for this condition is when too many things connected to the volt-meter. On the back of many Auto Meter volt-meters, there are three terminals. These are identified with the letters âSâ, âIâ, and âGNDâ.
